METHOD OF REINFORGING.

Specification of Letters Patent.

lpplication filed December 11, 1918. Serial No. 266,229.

To all whom it may concern:

Be it known that I, HENRY S. Wants, a citizen of the United States, residing, in the city of New York, borough of Manhattan, in.the county and State of New York, have invented a certain new and useful Method of Reinforcing, of which the following is a specification.

The invention relates to means for strengthening fishing-rods, golf clubs, and analogous yielding rods, shafts, braces and stays in which lightness and strength combined with a degree of resiliency are requisite qualities, and the object of the invention is to provide a method of reinforcing by which the strength may be increased without adding materially to the weight or detracting from the elasticity and fiexibilty of the article treated.

The accompanying drawings form a part of this specification and show four articles reinforced by my improved method.

Figure 1 is an elevation of a portion of a fishing-rod thus treated.

1Fig. 2 is am elevation of a reinforced golf 0 ub.

Fig. 3 is a face view of a tennis racket reinforced at the points of greatest strain.

Fig. 4 is an elevation showing a portion of a reinforced strut or brace.

Fig. 5 is a transverse section taken on the line 5-5 in the preceding figure.

Similar letters of reference indicate like parts in all the figures.

The a plication of the method is as follows loosely woven web in the form of a ribbon, referably a combination of silk, linen, an cotton, or a narrow strip of other material adapted to contact longitudinally, is tightly wound in an open spiral along the member to be reinforced, care being taken to la the ribbon smoothly and continuously an under stron tension. The ends of the ribbon are secure and the member with the ribbon thereon is then treated by applying an astringent or contractile solution thereto which shrinks the ribbon tightly upon the member. The character of the astringent or contractile solution, and the properties of the ribbon are such as to remain in the shrunken condition after the solution has dried, and the member with its tightly gripping ribbon may then be varnished or otherwise treated to protect the surfaces from moisture, such treatment dependlng somewhat upon the character of the member or article treated.

-In the section of fishing-rod shown in Fig. 1 the ribbon M is wound upon the rod A before varnishing, and the astringent or contractile solution applied with a brush. When dry the rod and ribbon are varnished and the section provided with the windings B and guide C and other accessories in all respects as usual.

A solution composed of one ounce of chlorid of sodium, eighty minims of alum, and two grains of chrome anilin, dissolved in thirty-two ounces of water, filtered, and applied at a temperature near the boiling point, is found to serve successfully and to shrink the ribbon to such a degree in practice that the ribbon hugs the member very closel and in some instances embeds itself slight y therein.

The ribbon M see Fig. 2, is applied to the shaft A of a golf club in a manner similar to that above described, and the shaft receives the windings B by which the ends of the ribbon are concealed, and is varnished as usual. The tennis racket shown in Fig. 3 has its handle A reinforced by aribbon M and the bow A reinforced on each side near its junction with the throat by narrower ribbons M passed through the interstices of the gut strings adjacent the bow, as will be understood. Windings B B provide-the required finish before varnishing. Figs. 4 and 5 show a strut or brace A which may be understood to be a member of the light framework of an airplane or like structure, reinforced by a ribbon M, similarly applied and contracted.

In flexing the treated member the strains along the convex or bowed face are resisted by the longitudinal tension of the ribbon which is in effect an integral part of the member and acts as a cantaliver in distributing the strains in both directions from the point of bending.

The invention maybe similarly applied to any yielding rods, shafts, braces, and stays, as for example archery bows, frames of airplanes, and light spars for yachts. The ribbon may be cotton and linen or wholly of either material alone, or of any suitable material, and may have the width and thickness required by the character of the service. Other solutions may be employed having the desired astringent or contractile properties.

v I clams:-

1. The method described of reinforcing rods, shafts, handles, and analogous members, consisting in winding a shrinkable ribbon along suchmember in an open spiral, securing the ends of said ribbon to such member, and treating said ribbon on such member with a contractile agent.

2. The method described of reinforcing flexible rods, shafts, handles, and analogous members, consisting in winding a shrinkable ribbon along such member in an open spiral, treating said ribbon on such member with an astringent contractile solution, drying said ribbon and member, and varnishing said ribbon and member.

3. The method described of reinforcing flexible rods, shafts, handles, and analogous members, consisting in winding a ribbon of webbing along such member in an open spiral, treating said ribbon on such member with a hot astringent, solution composed of chlorid of sodium, alum, and chrome anilin in a solvent, drying said ribbon and memfilier, and varnishing said ribbon and memln'testimony that Iclaim the invention above set forth I afix my signature.
